Crawl Space Moisture Problems

The home, built in 2011, had been occupied by the homeowner for two years. He noticed minor water in the crawl space and experienced cold floors in the winter, but an inspection by AFS revealed more significant issues. These included an ineffective vapor barrier and signs of water damage and efflorescence on the walls. The crawl space was also at risk of structural damage and contributing to higher energy costs because of moisture problems. Committed to making his forever home safe and efficient, the homeowner was eager to address these issues with a professional crawl space repair solution.

Proper Waterproofing and Encapsulation

AFS provided a thorough inspection and recommended a comprehensive waterproofing and encapsulation system. The plan included installing a crawl space drainage system with perforations to accept both soil and surface water, reducing the risk of clogs or failure, and adding two sump pumps to manage groundwater seepage by directing excess water to a sump pit and safely away from the home.

Efficient Dehumidification

A crew also attached thermal insulation panels with a reflective design to the walls to improve energy efficiency and maintain heat in the crawl space, installed a vapor barrier to keep the crawl space dry and prevent moisture intrusion, and set up a dehumidifier to regulate humidity levels and prevent mold growth. Additionally, secure, watertight crawl space doors were added to the home’s exterior.

Lasting Structural Support

In a separate project, another crew installed crawl space support jacks to reinforce and help lift problematic floor joists. These crawl space jacks are rated to support up to 24,860 pounds each, can be adjusted to fix sagging floors and floor joists, and provide lasting structural support.

Seeing the Positive Effects

The AFS crews transformed the crawl space into a dry, clean, and energy-efficient environment in just a few days. Throughout the process, the AFS team explained each step and ensured the homeowner understood the benefits of the chosen solutions.

The homeowner expressed satisfaction with the results, especially the increased energy efficiency and peace of mind knowing his crawl space is well-protected.

“AFS provides a superior solution in terms of technical knowledge and recommended products,” he said. “AFS demonstrated a willingness to listen and do whatever was needed to satisfy the customer.”

Crawl Space Encapsulation FAQs

Signs that your crawl space needs insulation include cold floors, high energy bills, musty odors, and visible moisture or mold in the crawl space.

Crawl space repair is worth it because it enhances energy efficiency and lowers energy bills by protecting the home from external elements such as wind and rain. Crawl space repairs also improve indoor air quality by minimizing mold spores and other air pollutants.

While it’s possible to install a crawl space vapor barrier yourself, it requires careful attention to detail, appropriate material selection, proper safety equipment, and thorough preparation of the crawl space. Professional installation is recommended to ensure proper overlap, sealing of seams, and coverage around obstacles, as improper installation can lead to moisture issues.
